  1. Redo it, definitely. It would not be a good IA if you had no data. It's a good IA, and very good talking points, instead use the old method as a reflection, such as in the evaluation. Talk about how such a method could seem practical but is not as usable as the new method. Data is important for the entire Physics IA, without it, you can't get higher than a 4, if you're lucky
  2. Sugar does not really do much. The liquid water is what causes the refraction alongside with the glass container. The sugar simply makes water more sweet and cloudy, it doesn't affect light as much, it would take a lot of sugar to affect it. I'm sorry but this experiment won't do well. But it can be altered. If you're keen on refraction, look at how different materials affect it, and the correlation. E.g. different types of glass, and maybe their masses. Dimensions. But I feel that refraction is too much of a closed ended topic, limiting your scope. But you're centred around waves, so maybe diffraction with single and double slit experiments, perhaps in water or wave oscillation with the container can be helpful. More open ended with more variables to control and talk about. Sorry I can't be much more help
  3. Hey I'm going to uni this year. From my experience, if you're looking at a good university. Physics SL won't cut it. Only Physics HL, and taking Physics HL also gives you advantage as you are more likely to be picked. For engineering Maths HL and Physics HL are much better, Maths Sl might be accepted, but its better both HL. Maths HL is basically required for Applied Mathematics so physics SL can cut it for Applied Maths. Just remember one thing though, there are tons, and I mean tons of online resources to help you with Maths and Physics. These are just some links that can help you in Physics: http://blog.prepscholar.com/the-best-ib-physics-study-guide-notes-sl-hl https://ibphysicsnotes.wordpress.com/ https://en.wikibooks.org/wiki/IB_Physics You can do it, it seems tough. But that's the point. IB Hl topics are basically the first year of Uni. So strive, work hard and you'll get into a top uni in Europe with HLs. Good luck man!
  4. Hey, Yes you can write it up as it is, but I suggest keeping the collected data, and also discharging capacitors under a specific condition to reduce the uncertainty and also to give you more to talk about in the IA. Having more data, whether used or not is helpful as some people do not have enough data needed for a full IA. I think you'll be marked down to a maximum of a high 6, or medium 6. 7s require good work, meaning littleuncertainty, all areas relevant are looked and an improved or addressed, rather not in the evaluation. So if you want a 7 or high 6, you'll need to add the dependence. All the best!
  5. Hey GK1, I did my EE in physics too, and there are a couple of things you need to keep in mind when writing your EE and research question. Firstly The research question needs to be precise but broad. Yours works very well I think, but if you can make it slightly more precise, it would ensure that the EE examiner won't mark you down. Science EEs are very strict like that, so adding another variable or perhaps looking at other applications can help to expand that question. Yes I think it is too simple, mainly because one variable is not enough for 4000 words, they are a lot. Once you get the topic going, they might cut down. But it's better to have a topic you write more than 4000 words about and cut down the words, than one you write less than 4000 words about and try to lengthen it. Physics EEs aren't just experiments or long IAs, they look at the future more. Meaning that you don't just look a the experiment, but also it's applications, its background. How it influences society, etc. So you broaden the topic by looking at other applications or other possible variables that influence this experiment, and then talk about those. A physics EE is constructed much like an IA, meaning Intro - Background - Section 1, in this case the experiment - Section 2, perhaps the outside applications - Conclusion Lastly, you have to love it. I love physics, and I loved doing my EE on metal foams, it was an incredible experience, and its demanding. So you have to be sure you like this topic before delving deeper. But if you do, you'll make something great, for sure. Physics is hard to love, but if you love it, the work will seem worth it
  6. Hey Befuddled, It doesn't matter the length of the sections, it's the overall word count that you need to focus on. 4000 words, roughly 3950/3900 is a better bet to ensure that you're within the word limit. If you want an answer to your question, it depends on what you're analysing. I did it in physics, so mine varied rapidly in the word count from 400-500 to 1200 words in a section, so it's just about the content. Just make sure you are concise and get your point across, then the word count comes in later.
  7. Hey legend, You have to understand, we can't help you write it or give you a research question. But we can try to help direct you to the right path, because the EE isn't something you can just pick up and write, you have to like it to do it right. Otherwise it is just too difficult, trust me I know. I did my EE in physics, on metal foams. I was thinking though of doing it on Tuned Mass Damper (TMD). It is an experimental EE, and can give you more flexibility on the variables. Otherwise, look online and see what you like about Physics, and then see if you can find a subject from there. (E.g. TMD could be topic 4 and 9 in the physics course) This is a good example
  8. Hey queenfeelnet, Sorry for the late response, hopefully it will still be relevant. You could take a video camera (phone for example) and take a video. Then use free software such as logger pro to plot the fluid dampening. For example, I did my IA last year in physics on eddy current braking, and used my phone to record videos of a magnet sliding down a ramp, and and magnet experiencing a braking effect when aluminium sheets where placed underneath. I then use logger pro to plot where the magnet was as time passed, and I was able to make a graph. Then you can export it. Use a website like Thepiratebay or another torrenting website / find logger pro online or through friends so that you can plot the video. If you need any more help, there will likely be youtube videos or tutuorials online on how to use logger pro. Best of luck, you got this! Alessandro
  9. Hey, Rezzurector Yes, and no. It's difficult, for example all materials after a certain thickness no longer matter for the restitution coefficient. Meaning that after a certain point, it'll just bounce back the same. But some materials are more absorbant than others, so changing their thickness could alter how they bounce. However, this also creates an uncertainty in your IA because how can you ensure, when you change the thickness of the material, that the material has the same materialistic properties that the previous thickness has. This could skew the results. I personally was encourgaing some friends last year to do something related to Tuned Mass Dampening. If you look on youtube, TMD explanation, there are some great videos using accelerometres that could help you, if you want. You'd just need Logic pro or some recording device, and accelerometre and you could link it to waves. Otherwise, your current IA sounds fun, you just need to be more aware of the uncertainty, and choosing the right materials beforehand, because you don't have too much time to waste.
  10. Hey lolkeinthatsghey, No, they aren't graded. But they are important, it is important because the IB will need to check to ensure you've done the required lab tests or experiments (ones which will be tested on SL and HL in paper 3) and also that you've done the minimum required hours. Don't fret, just try to pay attention and ensure that you understand the basic principles, they will help you in the future. Only the IA will be sent off to be externall moderated, outside of the exams, and the lap reports are just there to ensure that you know what that experiment or topic was. So try your best. Alessandro
  11. Hey songlines, Definitions should be the first sentences of your response. For example, if the question asks about demand, before answering the question you should star with "Demand is the willingness and ability of a consumer to buy a certain good at a certain price level" Then go on with the response. Definitions are always first, then the question. If you look at the markschemes, they always says definition of "..." before any other answers.
  12. Hey Ekzo, I think that likely the Macroeconomic section will include a question on cyclical unemployment, or some specific form of unemployment. It has been occuring in almost all the past papers I've been doing.
  13. I am unsure in the economics exam whether I need to draw the diagrams for all the questions on the graph apper provided by the examiners, or if I draw it ont he answer booklet alongside my response to the question. Any help would be appreciated, I'm stressing out over this
